What transmission rate can you get on POTS?

Plain Old Telephone Service (POTS) typically provides a maximum transmission rate of 56 Kbps for dial-up modems, although the actual speed can be lower due to line quality and distance from the service provider. POTS uses analog signals over copper telephone lines, which limits bandwidth compared to modern digital services. Therefore, while POTS can support basic voice communication effectively, it falls short for high-speed data transmission.
